Abstract
Description
Technical Field
[0001] This invention relates to the field of solar cell technology, and in particular to a stringing method and stringing equipment. Background Technology
[0002] In the field of photovoltaic module manufacturing, a cell string consists of several cells connected by solder ribbons. In BC type cell strings, the solder ribbons are only distributed on one side of the cells to enable current conduction between adjacent cells. Back-contact (BC) type cell strings have the characteristic of no grid lines on the front side, thus eliminating the light energy loss caused by the presence of grid lines on the front side of the cell string in traditional cell strings, maximizing the utilization of incident photon energy, and improving light energy conversion efficiency.
[0003] In the fabrication of BC-type solar cell strings, the input solar cells need to be diced, resulting in either Class A or Class B cells. These Class A and Class B cells are then arranged in different sequences to form either Class A or Class B solar cell strings. Current string bonding machines can only form one Class A or one Class B solar cell string at a time. These strings are then connected to form a long solar cell string. Finally, solder ribbons and films are applied to the long string, and after lamination, a BC-type photovoltaic module is formed. Producing only one Class A or Class B solar cell string at a time limits the production speed of the long solar cell string, resulting in low production efficiency.
[0004] Therefore, there is an urgent need to provide a stringing method and stringing equipment to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a stringing method and stringing equipment to solve the problem of low production efficiency of long battery strings in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stringing method, comprising: Two feeding mechanisms are used to supply the battery cells separately; Two dicing mechanisms are used to dic the solar cells supplied by the two feeding mechanisms to form Class A solar cells and Class B solar cells. A first pick-up element picks up a type A cell and a type B cell from one of the dicing mechanisms and places them on a first pre-arrangement platform to form a type A cell string or a type B cell string. Another first pick-up piece picks up the A-type and B-type battery cells from another dicing mechanism and places them on another first pre-arrangement platform to form a B-type battery string or an A-type battery string. A second picker is used to pick up a type A or type B battery string on a first pre-arrangement platform and place it in one of two second pre-arrangement platforms; Another second pick-up device is used to pick up a type B battery string or a type A battery string on another first pre-arrangement platform and place it on a second pre-arrangement platform that already has type A battery strings or type B battery strings to form a long string of type A batteries or a long string of type B batteries. The third pick-up component is used to move the long strings of Class A or Class B batteries to the stringing platform for solder ribbon attachment and film attachment.
[0007] As an alternative technical solution for the stringing method, the first pick-up unit simultaneously picks up and transfers both type A and type B solar cells.
[0008] As an optional technical solution for stringing, after picking up type A and type B solar cells, during the process of transferring them to the first pre-arrangement platform, the first picking unit combines type A and type B solar cells into a stack.
[0009] As an optional technical solution for stringing, type A battery strings and type B battery strings are alternately formed on the first pre-arrangement platform, and when one first pre-arrangement platform forms a type A battery string, the other first pre-arrangement platform forms a type B battery string.
[0010] As an optional technical solution for stringing, a type A battery string is first placed on a second pre-arrangement platform, followed by a type B battery string to form a long string of type A batteries; and a type B battery string is first placed on another second pre-arrangement platform, followed by a type A battery string to form a long string of type B batteries.
[0011] As an alternative technical solution for stringing, before the third picker moves the long string of type A or type B batteries from one second pre-arrangement platform to the stringing platform and returns from the stringing platform to another second pre-arrangement platform, the other second pre-arrangement platform completes the preparation of the long string of type B or type A batteries.
[0012] As an alternative technical solution for stringing, the cells are positioned before the dicing process.
[0013] A fabric stringing device for implementing the fabric stringing method described in any of the above technical solutions includes two sets of fabric stringing components, a third picking component, and a stringing platform. The fabric stringing components include a feeding mechanism, a dicing mechanism, a first picking component, a first pre-arrangement platform, a second picking component, and a second pre-arrangement platform arranged in sequence. The feeding mechanism is used to supply battery cells; the dicing mechanism is used to dice the battery cells to form type A battery cells and type B battery cells; one first pick-up member is used to transfer the type A battery cells and type B battery cells corresponding to the dicing mechanism to the corresponding first pre-arrangement platform to form type A battery strings or type B battery strings; another first pick-up member picks up the type A battery cells and type B battery cells on the corresponding dicing mechanism and places them on the corresponding first pre-arrangement platform to form type B battery strings or type A battery strings; a second pick-up member is used to pick up a type A battery string or type B battery string on one of the two second pre-arrangement platforms and place it on one of the two second pre-arrangement platforms; another second pick-up member is used to pick up a type B battery string or type A battery string on another first pre-arrangement platform and place it on a second pre-arrangement platform that already has type A battery strings or type B battery strings to form a long string of type A batteries or a long string of type B batteries. The third pick-up component is used to move the long strings of Class A or Class B batteries on the second pre-arrangement platform to the stringing platform and perform ribbon attachment and film attachment to form finished battery strings.
[0014] As a technical solution for a stringing device, the first pre-layout platform has a loading position and a unloading position. Along the left and right direction, the unloading positions of one first pre-layout platform and the unloading positions of another first pre-layout platform are arranged alternately.
[0015] As an alternative technical solution for stringing equipment, the stringing equipment also includes a testing platform, which is located downstream of the stringing platform and is used to test the finished battery strings.
[0016] The present invention has at least the following beneficial effects: This invention provides a stringing method and stringing equipment. The stringing method includes the following steps: supplying battery cells using two feeding mechanisms; dicing the battery cells supplied by the two feeding mechanisms using two dicing mechanisms to form type A battery cells and type B battery cells; picking up type A and type B battery cells from one dicing mechanism using a first pick-up piece and placing them on a first pre-arrangement platform to form type A battery strings or type B battery strings; and picking up type A and type B battery cells from another dicing mechanism using another first pick-up piece and placing them on another first pre-arrangement platform. The process involves: forming a Class B battery string or a Class A battery string; using a second pick-up piece to pick up a Class A battery string or a Class B battery string from a first pre-arrangement platform and placing it on one of two second pre-arrangement platforms; using another second pick-up piece to pick up a Class B battery string or a Class A battery string from another first pre-arrangement platform and placing it on a second pre-arrangement platform that already has Class A battery strings or Class B battery strings, to form a long string of Class A batteries or a long string of Class B batteries; using a third pick-up piece to move the long string of Class A batteries or the long string of Class B batteries to a stringing platform and performing ribbon attachment and film attachment to form a finished battery string.
[0017] Using the above method, both type A and type B battery strings can be formed on both first pre-arrangement platforms. Based on this, the second pick-up device transfers different types of battery strings from the first pre-arrangement platforms to the second pre-arrangement platform to form long strings of type A or type B batteries. Then, the third pick-up device transfers the long strings of type A or type B batteries to the stringing platform to complete subsequent operations. This greatly shortens the preparation time of the finished battery strings and improves the production efficiency of the finished battery strings. Attached Figure Description

[0021] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.
[0022] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0023] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.
[0024] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.
[0025] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.
[0026] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.
[0027] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.
[0028] Combination Figure 1 As shown, this embodiment provides a stringing method, which includes the following steps: two feeding mechanisms 100 supply battery cells respectively; two dicing mechanisms 200 dicing the battery cells supplied by the two feeding mechanisms 100 to form type A battery cells and type B battery cells respectively; a first picking member picking up the type A and type B battery cells from one of the dicing mechanisms 200 and placing them on a first pre-arrangement platform 300 to form type A battery strings or type B battery strings; another first picking member picking up the type A and type B battery cells from the other dicing mechanism 200 and placing them on another first pre-arrangement platform. On platform 300, a type B battery string or a type A battery string is formed; a second pick-up piece picks up a type A battery string or a type B battery string on a first pre-arrangement platform 300 and places it on one of two second pre-arrangement platforms 400; another second pick-up piece picks up a type B battery string or a type A battery string on another first pre-arrangement platform 300 and places it on a second pre-arrangement platform 400 that already has type A battery strings or type B battery strings, to form a long string of type A batteries or a long string of type B batteries; a third pick-up piece moves the long string of type A batteries or the long string of type B batteries to a stringing platform 500 and performs ribbon bonding and film bonding to form a finished battery string.
[0029] For example, a first picker is used to repeatedly pick up the required number of Class A and Class B battery cells from a dicing mechanism 200 and place them on a first pre-arrangement platform 300 to form a Class A battery string; another first picker is used to repeatedly pick up the required number of Class A and Class B battery cells from another dicing mechanism 200 and place them on another first pre-arrangement platform 300 to form a Class B battery string.
[0030] In another example, a second picker is used to pick up a string of type A batteries on a first pre-arrangement platform 300 and place it on one of two second pre-arrangement platforms 400; another second picker is used to pick up a string of type B batteries on another first pre-arrangement platform 300 and place it on a second pre-arrangement platform 400 that already has strings of type A batteries, so as to form a long string of type A batteries.
[0031] Using the above method, both type A and type B battery strings can be formed on the two first pre-arrangement platforms 300. Based on this, the different types of battery strings on the different first pre-arrangement platforms 300 are transferred to the second pre-arrangement platform 400 by the second pick-up device to form a long string of type A or type B batteries. Then, the long string of type A or type B batteries is transferred to the stringing platform 500 by the third pick-up device to complete the subsequent operations. This greatly shortens the preparation time of the finished battery strings and improves the production efficiency of the finished battery strings.
[0032] It should be noted that the difference between Class A and Class B solar cells lies in the arrangement of the grid lines. Class A cells can also be referred to as the first cell, and Class B cells as the second cell. The difference between Class A and Class B battery strings lies in the type of the first cell. A battery string whose first cell is Class A is called a Class A battery string, and a battery string whose first cell is Class B is called a Class B battery string. A long battery string consists of two battery strings; the difference between Class A and Class B long battery strings lies in the type of the first battery string. A long battery string whose first battery string is Class A is called a Class A long battery string, and a long battery string whose first battery string is Class B is called a Class B long battery string.
[0033] Positioning of the solar cells before dicing improves dicing accuracy and ensures the structural precision of Class A and Class B solar cells.
[0034] The first picker simultaneously picks up and transfers both Type A and Type B solar cells to improve the stringing efficiency of the battery strings. During the transfer of the Type A and Type B solar cells to the first pre-arrangement platform 300 after picking them up, the first picker combines the cells into stacks. Several stacks form a battery string. This design further reduces the finished product efficiency of the battery strings and places the stacking station on the first picker, helping to partially overlap the stacking time with the cell transfer time, thus improving the assembly efficiency of the battery strings. Stacking refers to partially overlapping Type A and Type B solar cells to achieve electrical connection.
[0035] Type A and Type B battery strings are alternately fabricated on the first pre-arrangement platform 300, with one first pre-arrangement platform 300 forming a Type A battery string while the other forms a Type B battery string. This method increases the production capacity of the first pre-arrangement platform 300, and the production of Type A and Type B battery strings depends solely on the type of the first battery cell. This can be achieved through the order in which the cells are picked up on the dicing mechanism 200 or through rotational motion during the stacking process, without affecting the battery string production cycle and ensuring production efficiency.
[0036] A type A battery string is placed first, followed by a type B battery string, on a second pre-arrangement platform 400 to form a long string of type A batteries; similarly, a type B battery string is placed first, followed by a type A battery string, on another second pre-arrangement platform 400 to form a long string of type B batteries. This method enables the preparation of both the long strings of type A and type B batteries. Specifically, in the long string of type A batteries, type A batteries are located upstream of the type B battery strings, and in the long string of type B batteries, type B batteries are located upstream of the type A battery strings. For example, in the long string of type A batteries, type A batteries are located to the left of the type B battery strings, and in the long string of type B batteries, type B batteries are located to the left of the type A battery strings.
[0037] In some embodiments, before the third pick-up component moves a string of Class A or Class B batteries from one second pre-arrangement platform 400 to a stringing platform 500 and returns from the stringing platform 500 to another second pre-arrangement platform 400, the other second pre-arrangement platform 400 completes the preparation of the Class B or Class A battery strings. This method effectively utilizes the transport time of the third pick-up component, avoids waiting during the transport process, and improves the production efficiency of Class A or Class B battery strings.
[0038] This embodiment also provides a stringing device for implementing the stringing method in any of the above embodiments. The stringing device includes two stringing assemblies, a third pick-up component, and a stringing platform 500. Each stringing assembly includes a feeding mechanism 100, a dicing mechanism 200, a first pick-up component, a first pre-arrangement platform 300, a second pick-up component, and a second pre-arrangement platform 400 arranged sequentially. The feeding mechanism 100 supplies battery cells. The dicing mechanism 200 dices the battery cells to form Class A and Class B battery cells. One first pick-up component transfers the Class A and Class B battery cells from the corresponding dicing mechanism 200 to the corresponding first pre-arrangement platform 300 to form Class A or Class B battery strings. Another first pick-up component picks up the corresponding cells from the dicing mechanism 200. Type A and Type B battery cells are placed on corresponding first pre-arrangement platforms 300 to form Type B or Type A battery strings. A second pick-up member picks up a Type A or Type B battery string from one of the first pre-arrangement platforms 300 and places it on one of two second pre-arrangement platforms 400. Another second pick-up member picks up a Type B or Type A battery string from another first pre-arrangement platform 300 and places it on a second pre-arrangement platform 400 that already has Type A or Type B battery strings to form a long Type A or Type B battery string. A third pick-up member moves the long Type A or Type B battery string from the second pre-arrangement platform 400 to a stringing platform 500 for ribbon bonding and film bonding to form a finished battery string. This structure improves the production efficiency of finished battery strings.
[0039] In some embodiments, the first pre-arrangement platform 300 has a loading position 310 and a unloading position 320, with the unloading positions 320 of one first pre-arrangement platform 300 and the unloading positions 320 of another first pre-arrangement platform 300 arranged alternately in the left-right direction. This arrangement allows the second picking component to move only in the width direction, improving operational efficiency. The width direction is the vertical direction. For example, in the first instance, a first pre-arrangement platform 300 on top produces a type A battery string, and a second pre-arrangement platform 300 below produces a type B battery string. A second pickup on top picks up a type A battery string and places it on the second pre-arrangement platform 400 on top, located on the left side, while a second pickup on the lower side picks up a type B battery string and places it on the second pre-arrangement platform 400 on top, located on the right side, thus forming a long string of type A batteries. In the second instance, a first pre-arrangement platform 300 on top produces a type B battery string, and a second pickup on the lower side produces a type A battery string. A second pickup on top picks up a type B battery string and places it on the second pre-arrangement platform 400 on top, located on the left side, while a second pickup on the lower side picks up a type A battery string and places it on the second pre-arrangement platform 400 on top, located on the right side, thus forming a long string of type B batteries.
[0040] In some embodiments, the stringing device further includes a detection platform 700, which is located downstream of the stringing platform 500 and is used to detect finished battery strings. The upstream platform is located on the left, and the downstream platform is located on the right. Exemplarily, two detection platforms 700 are arranged at intervals in the vertical direction, one platform 700 is used to detect Class A battery strings, and the other platform 700 is used to detect Class B battery strings. The detection method employs PL detection (photoluminescence detection) or EL detection (electroluminescence detection).
[0041] In some embodiments, the stringing device further includes a conveyor 800, which is located downstream of the stringing platform 500 and below the detection platform 700, for conveying the tested A-type and B-type battery strings to the outside. The stringing device also includes a positioning mechanism 600, which is located between the feeding mechanism 100 and the dicing mechanism 200, for positioning the battery cells.
[0042] In some embodiments, the stringing device further includes a ribbon preparation component and a membrane preparation component, wherein the ribbon preparation component is used to prepare the ribbon and attach the ribbon to the cell, and the membrane preparation component is used to prepare the membrane and attach the membrane to the ribbon.
[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
